Haha, pink bunny slippers with ears would be what I'd have in store for Rob, in addition to Tom's super secret setup :)

Thanks Tom! The dual, integrated to the trigger guard paddle release can be used as intended: index finger pressing down on either lever, or as old school HK G3 /MP5 release (with the supporting hand's thumb) :D

Haha make it pay per view! <lmao>

All I know is there will be pictures plastered all over the interwebz ;D

Haha we're partially responsible for the special AR Tom's putting together for Rob, thanks to Tom :cookoo: ;) <thumbsup>

Thanks Tom :D We have been working together with Randy Cain at R+D Precision, who was part of the development team before we obtained the rights to what is now the BAD-BDM. It was a great product when it was released in limited numbers, after we got our hands on the design, we spent another year refining it further. It was one of the projects that absorbed a lot of time and resources, the end result will show the typical attention to detail and quality we're known for :)

Drew and Robocop <thumbsup> Actually, all of you guys. It was Drew's idea to have members here rate it on Brownells :)

Thank you guys, especially Drew :D

:D

Cool! ;D

Many of you know we've been talking about playing with the throw distance for months. We've made close to a dozen prototypes with various throw distances. The reason for this is simply the inevitable slack exists when the selector is rotated to either FIRE or SAFE. The detent holes must necessarily be slightly larger than the detent itself, or the detent can't go into the detent holes. The detent holes must necessarily be slightly larger than the detent itself, or the detent can't go into the detent holes. This slack and angle of the detent holes are the reason for the 2 to 4 degrees of movement when the detent is engaged, with the selector rotated to either FIRE or SAFE. Though with the latest development we did on the detent groove and detent holes, the slack has been reduced, we are always looking for ways to further improve things. With a 45 degree selector, 4 degree of movement each way is more exaggerated than it is on a 90 degree selector. With triggers that are spec, or close to spec, the 45 degree selector cannot be rotated from SAFE to FIRE by pressing on the trigger, the experiment with 50 to 55 degree selectors has nothing to do with this issue that's really a tolerance stacking problem caused by triggers that are too beyond spec measurements. No decision has been made on these longer throws. We're of the opinion that 45 degree throw is the optimum throw arc for a short throw selector. HK, FN, and other manufacturers apparently feel the same way, for their throw arcs sometimes are even shorter. In other news, a short throw M16 selector is also now in development ;D

The problem we identified with the AR Gold trigger was the trigger's rear extension is too tall. The trigger's rear extension interfaces with the selector's middle, flat section. Our middle, flat section measures 0.240, a cast selector's mid flat section is about 0.230. The milspec is taller than both of these. We've reduced the center diameter couple of times to make it more compatible with aftermarket triggers that deviate from Colt specs, in the case of the AR Gold trigger, it's just too much. Below, left is my receiver with an RRA trigger, hammer uncocked. Right is an AR Gold trigger, hammer uncocked. The trigger's rear "tang" is super elevated, and can cause problems with either the 45 or 90 degree selector.

There had been reports of the 45 degree selector's compatibility with couple of triggers, so I will elaborate this issue a little. So far, we know of two triggers that seem to have issues with the 45 degree selector: AR Gold, and Wilson Combat's TR TTU (the original TTU works fine). To this, I have to add that these triggers have heretofore caused issues with the 45 degree selector, but they may not be ALL incompatible. We do not have an AR Gold trigger, so this finding is limited to the TR TTU. The first generation of TTU used to have set screws on the bottom to allow some height adjustment, subsequent models have springs, the only way to “adjust” them is by clipping off coils. Without these springs, the trigger will fire even when the selector is on SAFE. With them installed, they push the entire housing, and the trigger’s rear tail up and puts it in contact with the selector center. This isn’t a problem with 90 degree selectors, as the rotation is a full 90 degrees, the travel is too long for the trigger to complete a rotation to FIRE. With a short throw selector, the tail touches the leading edge of the flat area of the selector and can rotate it out of detent engagement. Partially this has to do with the angle the detent hole are cut, we’ve since changed over to a different angle that allows much less movement when the detent is engaged. When the lever is on SAFE and perfectly parallel to the bore, the trigger cannot rotate the selector out of detent engagement. When there’s a light movement in the selector, the trigger has a better chance of rotating it out of detent engagement. Also at fault is the taller trigger “tail”. When a manufacturer improves a trigger, by definition it is already not in original specs. Our selectors are designed for in spec receivers and triggers, as long as both are close enough to the original specs, the tolerance stacking issue is mostly a moot point. Our favorite triggers are the Geissele triggers, all versions of Geissele are compatible with the 45 degree selectors, as well as factory, RRA, JP, KAC, etc. Since being on the market in late 2010, we've had but two or three reports of incompatibility, so this is definitely not a wide spread symptom.

<thumbsup> The free lever exchange program is still relatively unknown to many users, it's not for lack of trying though, we make no secret of the program and tell everyone about it every change we get ;D

Couple of unofficial rules: 1. If a customer orders a patch, hat, magnet, swag is automatically thrown in 2. If a customer requests a drawing on the package, swag is automatically included 3. Repeat customers always get swag 4. Mention 308ar.com, or any clever message in shipping instructions = swag :D A customer asked us to draw a monkey fighting a shark on the box, well I'm no artist so I cobbled this up for him :)

Rainier Arms forged 45/90 compatible receiver is $145 <thumbsup>

To give the user a comfortable high hold on the pistol grip :)

The crank is a thumb side lever, you should keep it Robo ;D

Here it is, it's something mm made and suggested. The one shown in the pics was manually modified, the production version will look very close to it. Since it was mm's inspiration and creation, we'll probably adopt its namesake as well: SRT (short, relieved thick). Everyone knows our naming convention, while to the point, is rather boring, so I quite like the new name given to the 7th lever. [img width=810 height=607]http://i75.photobucket.com/albums/i314/Duffypoo/ax55635.jpg I told ya that the pics of the 7th lever were floating out there :p The short lever, while being the most popular trigger finger side lever, rubs against the top of the user's trigger finger. By relieving a short lever's tip corner where most of the interference takes place, it makes the SRT more comfortable to use on the trigger finger side. It's always a trade off, removing material usually means removing some usable leverage, in the case of the SRT lever, the leverage isn't affected proportionally to the material removed, so we deem it a good tradeoff :)

Thank you :)

Thank you! Chris has been using our selectors for a long time, we see them on his carbines, now it's official <thumbsup>

Battle Arms Development is proud to announce it is now a Costa Ludus Syndicate :D Battle Arms on Costa Ludus

I see, sorry to hear :(

What are you guys talking about? ???
